Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0028] see figure 2 and image 3 , an embodiment of the present invention provides an electrode sheet cutting method, which includes the following steps:
[0029] Step 1: The cutting position of the cutting jig cuts the electrode sheet along the cutting line 120 , and forms the waste strip 200 and the electrode strip 100 on both sides of the cutting line 120 . Wherein, the cutting fixture is a laser cutting head. The laser cutting head vaporizes the materi...

The invention provides an electrode slice cutting method comprising: Step 1, an electrode slice is cut by the cutting position of a cutting fixture along a cutting line to form a waste band and an electrode slice band at both sides of the cutting line separately; Step 2, the cutting position of the cutting fixture shifts to the waste band from a cutting point, and stops at the waste band in case of abnormality of the cutting state of the electrode slice; and Step 3, the cutting position of the cutting fixture shifts to the cutting line from the waste band after the abnormality of the cutting state of the electrode slice is eliminated, and moves to the cutting point, and Step 1 is repeated. The invention also provides an electrode slice cutting device. According to the device and the method, provided by the invention, the technical problem that the product quality is affected by spots formed at the cutting point on the cutting line since the cutting fixture remains on the cutting line for a long time when the cutting work stops is solved, and the defects of the electrode slice are avoided; and the yield is improved, and materials are saved.
Description
technical field [0001] The invention relates to the field of electrode sheet cutting, in particular to an electrode sheet cutting device and an electrode sheet cutting method. Background technique [0002] like Figure 1a and Figure 1b The pole piece raw material includes a coated area 10 and a non-coated area 20, the cutting head cuts the non-coated area 20 of the pole piece raw material covered on the driving roller, and the driving roller drives the pole piece raw material to feed. The cutting head cuts along the cutting line 102 on the raw material of the pole piece to form regularly zigzag-shaped tabs 30 interspersed with each other. However, when the cutting work is abnormal, for example, the cutting size deviation, the difficulty in feeding the raw material of the pole piece, etc., the driving roller stops driving. At this time, the cutting position of the cutting head stops relative to the raw material of the pole piece. When the cutting position stops for a long t...
